Manufacturing sales rose 2.6 per cent to $49.2-billion in September, their third straight monthly increase.
Statistics Canada reports the gain largely reflected higher sales in the petroleum and coal products and transportation equipment industries.
Constant-dollar manufacturing sales were up 1.8 per cent.
Higher sales were reported in 10 of 21 industries, representing 60.5 per cent of total manufacturing.

The September increase was partly offset by a 3.0 per cent decline in food industry sales.
